Continuous Residence and Physical Presence, Explained

These are two separate tests, and you must pass both. Continuous residence asks whether you kept living in the United States without long absences. A trip of more than 6 months is presumed to break it, and a trip of 1 year or more breaks it automatically. Physical presence asks whether you were actually in the country for at least half the required period: 913 days in 5 years, or 548 days in 3 years under the spouse rule. You can pass one and fail the other.

Continuous residence: the rules

You need continuous residence for 5 years as a green card holder (3 years under the spouse rule), right up to the day you file. It must continue from filing until your oath.

How absences are treated:

Each trip is judged separately. Two 5-month trips in a year don't add up to a break, but they do count heavily against physical presence.

Rebutting the presumption for 6 to 12 month trips

If you were away more than 6 months but less than a year, you must show you didn't give up your U.S. residence. Factors USCIS considers include:

Useful evidence includes:

Explain the reason for the trip, such as caring for a sick parent or a temporary work assignment, and document it.

What doesn't protect continuous residence

Form N-470: preserving residence for work abroad

If you'll be abroad for a year or more for qualifying work, you can apply to preserve your continuous residence with Form N-470 (fee: $420 as of October 2026). Qualifying employers include:

In general you must have at least 1 year of unbroken physical presence as a green card holder before you file the N-470, and you must file it before you've been abroad for a year. Religious workers have their own N-470 rules. An approved N-470 protects continuous residence, but in most cases not physical presence.

After a break: when can you apply again?

If a trip of a year or more broke your continuous residence, the clock starts over. Under the 5-year rule, the USCIS Policy Manual says you may file 4 years and 1 day after you returned. Because part of the long absence still falls within the 5-year period at that point, you'll have to rebut the presumption of a break. The Policy Manual notes that applying 4 years and 6 months after returning avoids the presumption, since the part of the absence left in the period is then under 6 months. For the spouse rule, check the Policy Manual or ask an attorney how this works with the 3-year period.

If a 6 to 12 month trip broke continuous residence and you can't rebut the presumption, it may be simplest to wait until that trip is more than 5 years in the past (or 3 years under the spouse rule).

Physical presence: counting the days

Physical presence is a simple count of days inside the United States during the required period:

USCIS counts the day you leave and the day you return as days in the United States. So a trip from March 1 to March 10 counts as 8 days abroad, not 10.

How to count:

  1. List every trip in the last 5 years (or 3), with exact departure and return dates.
  2. Count the full days abroad for each trip, without the departure and return days.
  3. Add them up and subtract from 1,826 days (5 years) or 1,095 days (3 years).
  4. Check that the result is at least 913 (or 548).

Get your official travel history from CBP's I-94 website to check your dates. The officer will compare your N-400 with government records.

Real-world examples

Also required: 3 months in your state or district

Separately, you must have lived in your state or USCIS district for at least 3 months before filing. Moving across states right before filing can delay your eligibility. See the full naturalization eligibility requirements, and before any trip after filing, read traveling while your N-400 is pending.

Frequently asked questions

Does a trip of exactly 6 months break continuous residence?

The presumption applies to absences of more than 6 months. A trip of 6 months or less generally doesn't create the presumption, but keep proof of your U.S. ties anyway, and count the days carefully.

Do trips to Canada or Mexico count?

Yes. Every trip outside the United States counts for physical presence and must be listed on the N-400, including day trips across the border.

Does a reentry permit protect my naturalization timeline?

No. A reentry permit helps you keep your green card during a long absence, but it doesn't preserve continuous residence for naturalization. Only an approved N-470 does, and only for qualifying employment.

Can I travel after filing my N-400?

Yes, but continuous residence must continue until your oath, and you must attend biometrics and the interview. Keep trips short, and keep your mail and notices under control.
